$ scanimage --help -Av -d "brother2:bus1;dev1"
Usage: scanimage [OPTION]...
Start image acquisition on a scanner device and write image data to
standard output.
Parameters are separated by a blank from single-character options (e.g.
-d epson) and by a "=" from multi-character options (e.g. --device-name=epson).
-d, --device-name=DEVICE use a given scanner device (e.g. hp:/dev/scanner)
--format=pnm|tiff|png|jpeg file format of output file
-i, --icc-profile=PROFILE include this ICC profile into TIFF file
-L, --list-devices show available scanner devices
-f, --formatted-device-list=FORMAT similar to -L, but the FORMAT of the output
can be specified: %d (device name), %v (vendor),
%m (model), %t (type), %i (index number), and
%n (newline)
-b, --batch[=FORMAT] working in batch mode, FORMAT is `out%d.pnm' `out%d.tif'
`out%d.png' or `out%d.jpg' by default depending on --format
This option is incompatible with --output-file. --batch-start=# page number to start naming files with
--batch-count=# how many pages to scan in batch mode
--batch-increment=# increase page number in filename by #
--batch-double increment page number by two, same as
--batch-increment=2
--batch-print print image filenames to stdout
--batch-prompt ask for pressing a key before scanning a page
--accept-md5-only only accept authorization requests using md5
-p, --progress print progress messages
-o, --output-file=PATH save output to the given file instead of stdout.
This option is incompatible with --batch.
-n, --dont-scan only set options, don't actually scan
-T, --test test backend thoroughly
-A, --all-options list all available backend options
-h, --help display this help message and exit
-v, --verbose give even more status messages
-B, --buffer-size=# change input buffer size (in kB, default 32)
-V, --version print version information
Output format is not set, using pnm as a default.
